Abstract	This thesis aims at deepening and improving the methods to characterise the response of diamond detectors in view of an upgrade of the radiation monitor of the Belle II particle- physics experiment. Three types of radiation are used: α and β particles, and, for the first time in this kind of characterisation, X-rays. I employed a novel method to characterise the diamond-sensor response to β and X radiation, which exploits a silicon diode as a reference to minimise systematic uncertainties due to the poor knowledge of the radiation sources. I improved the simulation of the experimental setup over that previously used in the characterisation with α radiation. The results that I obtained represent important steps forward in the characterisation techniques for diamond sensors to be used for the radiation-monitor upgrade.
